def get_id_size():
    read_file = pandas.read_csv('poem_info.csv')
    poemid = (read_file[['poemname']])
    poemsize = (read_file[['poemsize']])
    return (poemid, poemsize) #this is the columns i want in my new.csv file

    with open('poem_data.csv', 'w') as outfile:
        # write header
        outfile.write('poemid,poemsize,cli,ari\n')

        cli = calculate_cli
        ari = calculate_ari
